Dervish raptor farming

My experience so far is that it can definitely handle the nestlings. So far I haven't been able to take out Rekoff, but it could be that I'm rushing the pre-spike phase. Still, just taking on the Nestlings is quick and easy, just so long as Vow of Strength (akin the the Warrior's Hundred Blades) doesn't get interrupted. Over time I'm sure this build will be refined.
